Blind flange lockout devices
Blind flange lock-outs are used during maintenance on piping. When the blind flange locking device is in place and mounted on the nuts between two parts of pipes the device prevents flanges to be placed or removed.
Blind flange lockouts are available for different bolt sizes and bolt spacing. Each size has a range between which all deviating bolt sizes and distances will fit.
Because block and bleed work often takes place outdoors and under different environmental conditions, blind flange interlocks are resistant to large temperature differences, humidity and more than 30 chemicals. *
* Use safety tags and safety padlocks that are suitable for outdoor use.
